Across three studies, we examined the role of self-evaluation in predicting conspiracy beliefs. Previous research linked the endorsement of conspiracy theories to low self-esteem.We propose that conspiracy theories should rather be appealing to individuals with exaggerated feelings of self-love, such as narcissists, due to their paranoid tendencies. In Study 1 general conspiracist beliefs were predicted by high individual narcissism but low self-esteem. Study 2 demonstrated that these effects were differentially mediated by paranoid thoughts, and independent of the effects of collective narcissism. Individual narcissism predicted generalized conspiracist beliefs, regardless of the conspiracy theories implicating in-group or out-group members, while collective narcissism predicted belief in out-group but not in-group conspiracies. Study 3 replicated the effects of individual narcissism and selfesteem on the endorsement of various specific conspiracy theories and demonstrated that the negative effect of self-esteem was largely accounted for by the general negativity towards humans associated with low self-esteem.

Narcissism, self-esteem and the endorsement of conspiracy theories Although conspiracy theories are often treated as harmless entertainment, they can have serious societal consequences (Douglas, Sutton, Jolley, & Wood, 2015). For example, exposure to conspiracy theories can decrease political engagement or pro-environmental behavior (Jolley & Douglas, 2014a;2014b). If widespread conspiracy theories affect the society, then it seems important to understand psychological factors underlying conspiracy beliefs. One prevalent hypothesis in this line of inquiry has been that conspiracy theories are usually endorsed by individuals who show poor psychological adjustment or are in some way socially disadvantaged. Conspiracy beliefs have been linked to powerlessness (AbalakinaPaap, Stephan, Craig, & Gregory, 1999), feelings of relative deprivation (Bilewicz, Winiewski, Kofta, & Wójcik, 2013), anomie (Abalakina-Paap et al., 1999;Imhoff & Bruder, 2014), lack of personal control (Whitson & Galinsky, 2008; cf. Bruder, Haffke, Neave, Nouripanah, & Imhoff, 2013), uncertainty (van Prooijen & Jostmann, 2012Whitson, Galinsky, & Kay, 2015), and being a member of a disadvantaged group (Abalkina-Paap et al., 1999;Crocker, Luhtanen, Broadnax, & Blaine, 1999;Goertzel, 1994). It has been theorized that belief in others´ conspiratorial actions that unfairly undermine one's own efforts, can serve to protect feelings of self-worth (Robins & Post, 1997).In line with this reasoning, Abalkina-Paap and colleagues (1999) proposed that conspiracy beliefs should be endorsed by people with low self-esteem "because this permits them to blame others for their problems" (p. 644). So far, however, evidence linking conspiracy beliefs to low s...
